Please fix this issue, provide a way to read legacy data or convert it to the modern format.

This made the issue worse, not better. By not being able to read the older legacy format of the game save, it will crash the client if we update. Please revert or fix.

This made impossible to load serialized files from older engine versions meaning loss of data.

After this update on b16 when i try to deserialize a serializable class that contains a list with a primitive type and a sorteddictionary with key being a string and value being another serializable class it crashes the player (il2cpp only)
